many popular OLED and LCD display panels.
Powerful graphics, text, image, animation and
countless more features are built right inside the
chip. It offers a simple yet effective serial interface
to any host micro-controller that can communicate
via a serial port. All screen related functions are
sent using a simple protocol via the serial
interface. Serial commands may comprise of a
single byte or multiple bytes of data depending on
the command type. The serial platform allows
users to develop their application using their
favourite
micro-controller
and
software
development tools. In short, it offers one of the
most flexible Graphics controllers available that
will run ‘out of the box’.
All of the data and control signals are provided by
the chip to interface directly to the display. Simply
choose your display and interface it to the
GOLDELOX-SGC beside your host controller on
your application board. This offers enormous
advantage to the designer in development time
and cost saving and takes away all of the burden of
low level design. The GOLDELOX-SGC can be
considered to be another Black Box which the
designer knows will work and therefore more
design emphasis can be put into the final User
Interface and overall high level design criteria.

2.3 Serial Port - UART
The GOLDELOX-SGC has a dedicated hardware
UART that can communicate with a host microcontroller via its serial port. This is the main
interface used by the host micro-controller to
communicate with the GOLDELOX-SGC to send
commands and receive back data.
The primary features are:
• Full-Duplex 8 bit data transmission and
reception through the TX and RX pins.
• Data format: 8 bits, No Parity, 1 Stop bit.
• Auto Baud feature.
• Baud rates from 300 baud up to 256K baud.
A single byte serial transmission consists of the
start bit, 8-bits of data followed by the stop bit.
The start bit is always 0, while a stop bit is always
1. The LSB (Least Significant Bit, Bit 0) is sent out
first following the start bit. Figure below shows a
single byte transmission timing diagram.
TX pin (Serial Transmit):
Asynchronous Serial port Transmit pin, TX.
Connect this pin to host micro-controller Serial
Receive (Rx) signal. The host receives data from
GOLDELOX-SGC via this pin.

complex sounds and audio from its SOUND pin. A
simple speaker circuit as shown below can be
utilised. For a complete list of sound commands
please refer to the separate document titled
'GOLDELOX-SGC-COMMANDS-SIS.pdf'.
SOUND pin (Sound-Audio Output):
Sound and audio waveforms are generated from
this pin. Connect this pin to a simple speaker
circuit detailed above. If unused then this pin
must be left open or floating.
2.5 Button-Switch Interface
The Serial port is also the primary interface for
updating and programming the GOLDELOX-SGC
with specific display drivers and for future serial
command upgrades and enhancements. Please
refer to Section 5. In-Circuit-Serial-Programming
(ICSP) for more details.

3. Host Interface
The GOLDELOX-SGC provides both a physical and a
software interface to its host.
3.1 Physical Interface - UART
The physical interface to the host is provided by
the UART and the host communicates to the
device via this serial link. The host uses this
physical interface to send commands and data.
Serial Data Format: 8 Bits, No Parity, 1 Stop Bit.
3.2 Software Interface – Command Set

For a complete detailed list of commands refer to
the separate document titled:
“GOLDELOX-SGC-COMMANDS-SIS.pdf”
Each command is made up of a sequence of data
bytes. When a command is sent to the module
and the operation is completed, the module will
always return a response. For a command that has
no specific response the module will send back a
single acknowledge byte called the ACK (06hex), in
the case of success, or NAK (15hex), in the case of
failure.
Commands having specific responses may send
back varying numbers of bytes, depending upon
the command and response. It will take the
module a certain amount of time to respond,
depending on the command type and the
www.4d-Labs.com
Page 9 of 20
GOLDELOX-SGC
Data Sheet
operation that has to be performed. If the device
receives a command that it does not understand it
will reply back with a negative acknowledge called
the NAK (15hex). Since a command is only
identified by its position in the sequence of data
bytes sending incorrect data can result in wildly
incorrect operation. Comma
3.3 Auto-Baud Setup
The GOLDELOX-SGC has an auto-baud feature
which can automatically detect the host speed
and can set its internal baud rate to operate from
300 to 256K baud. Prior to any commands being
sent to the device, the host must first initialise it
by sending the auto-baud character ‘U’ (55hex)
after any power-up or reset. This will allow the
device to determine and lock on to the baud rate
of the host automatically without needing any
further set-up. Once the GOLDELOX-SGC has
locked onto the host baud rate it will respond with
an ACK byte (06hex).
Auto-Bauding must be performed each time the
GOLDELOX-SGC is powered up or reset.
4. Power-Up and Reset
When the GOLDELOX-SGC comes out of a power
up or external reset, a sequence of events must be
observed before attempting to communicate with
the module:
• Allow up to 500ms delay after power-up or reset
for the module to settle without a uSD card
inserted. If a uSD card is inserted the
initialisation time of the particular card will need
to be added, better quality cards tend to
initialise in about 75ms or quicker, lower quality
ones can take up to a second. Do not attempt to
communicate with the module during this
period. The module may send garbage on its TX
Data line during this period, the host should
disable its Rx Data reception.
• Within 100ms of powering up, the host should
make sure it has its Tx line pulled HIGH. If the
host Tx (device RX) is LOW or floating after the
100ms period, the device may misinterpret this
as the START bit of the auto-baud character and
lock onto some undesired baud rate. If the host
has a slow wake up time, i.e. less than 100ms,
its Tx line maybe floating. This can be easily
resolved by adding a pull up resistor on the host
Tx line which will ensure the device does not
encounter a false start bit. The pull up resistor
can be any value within 10K to 100K.
• The host transmits the auto-baud character
(capital U, 55hex) as the first command so the
device can lock onto the host’s baud rate.

GOLDELOX-SGC
Data Sheet
Once the host receives the ACK the GOLDELOXSGC is now ready to accept commands from the
host.
4.1 Splash Screen on Power-Up
The GOLDELOX-SGC will wait up to 5 seconds for
the host to transmit the Auto-Baud command (‘U’,
55hex). During this period the attached display
will remain blank. If the host has not transmitted
the Auto-Baud command by the end of this period
the GOLDELOX-SGC will display a built-in splash
screen. If the host has transmitted the Auto-Baud
command, the screen will remain blank. This wait
period is for those customer specific applications
where the splash screen is undesired.
4.2 4DSL Memory Card Script Program
The complete command summary for the
GOLDELOX-SGC is listed in the previous section 3
of this document. The command execution is not
only limited to the host sending these via the
serial interface. The majority of them can be
composed as a script and written into memory
card. A 4DSL script program is a sequence of those
commands that reside and can be executed from
inside the memory card and these can be a
combination of graphics, text, image, video and
audio commands. Complete list of commands
available for the scripting program is listed in a
separate document titled:
“GOLDELOX-SGC-COMMANDS-SIS.pdf”
4.3 Auto-Run Card Script Program
The GOLDELOX-SGC has a feature that will auto
run a preloaded script program, on the
uSD/uSDHC memory card, on power-up. If the
SWITCH input (pin 27) is connected to GND (on
power-up) and if there is a script program present
in the memory card then the device will auto run
the script program. This is a useful feature for
those stand alone applications where the device
does not require a host controller to play a slide
show of images, video clips, etc.

5. In Circuit Serial Programming-
ICSP
The GOLDELOX-SGC is a custom graphics
controller. All functionality including the high level
commands are built into the chip. This chip level
configuration is available as a PmmC (Personalitymodule-micro-Code) file.
A PmmC file also contains all of the low level
micro-code information (analogy of that of a soft
silicon) which define the characteristics and
functionality of the device. The ability of
programming the device with a PmmC file
provides an extremely flexible method of
customising as well as upgrading it with future
enhancements.
A PmmC file can only be programmed into the
device via its serial port and an access to this must
be provided for on the target application board.
This is referred to as In Circuit Serial Programming
(ICSP). Figure below provides a typical
implementation for the ICSP interface.
ICSP Interface
The PmmC file is programmed into the device
with the aid of “PmmC Loader”, a PC based
software tool. To provide a link between the PC
and the ICSP interface a USB to Serial converter is
required. A range of custom made micro-USB
devices such as the uUSB-MB5 and the uUSB-CE5
are available from 4D Systems.

The 4D FAT Controller is a free software tool to test
all of the functionality of the GOLDELOX-DOS,
GOLDELOX-SGC and the PICASO-SGC devices and
their respective modules. It is useful in learning
about how to communicate with the chips and the
modules. For the GOLDELOX-SGC and the PICASOSGC it can also simulate most of the operation of
the device and assist in the creation of simple
scripts, either simulating the execution of those
scripts and / or downloading them into a
uSD/uSDHC card for execution on the display.
